PIN ASSIGNMENTS
Pin 1— V_OUT — Inverting charge pump output.
Pin 2 — V_IN — Input to the positive power
supply.
Pin 3 — C1- — Negative terminal to the charge
pump capacitor.
Pin 4 — GND — Ground reference.
Pin 5 — C1+ — Positive terminal to the charge
pump capacitor.
TYPICAL PERFORMANCE CHARACTERISTICS
V_IN = +3.3V, C1 = C2 = C3 = 10µF for SP6828, C1 = C2 = C3 = 3.3µF for SP6829, and T_AMB = 25^oC unless
otherwise noted. The SP6828/6829 devices use the circuit found in Figure 19 when obtaining the following typical
performance characteristics (unless otherwise noted).
